Homework Help: Help With Physics Terms (Nuclear)

  1. Apr 9, 2012 #1
    Can someone please help me figure out which terms match these definitions for nuclear physics?

    1. Process in which a nuclide is transformed into a nuclide of a different element.

    2. Total number of nucleons remains constant.

    3. A radioactive transformation of a nuclide in which a bound electron merges with its nucleus.

    4. A particular type of radiation emitted by a radioactive substance.

    5. A radionuclide that upon disintegration yields a specific nuclide.

    6. The division of an atomic nucleus into parts of comparable mass.

    7. The mass of fissionable material of a particular shape that is just sufficient to sustain a nuclear chain reaction.


    Also I was wondering if an alpha particle has enough kinetic energy can it penetrate the nucleus of an atom and establish strong nuclear force?

    Alright, but I'm not very sure of myself right now.

    1. beta decay
    2. no clue
    3. electron capture
    4. no clue
    5. parent nuclide
    6. nuclear fission
    7. critical mass?

    And I'm guessing that the alpha particle would be able to penetrate.

    For 2, "Total number of nucleons remains constant", the same number of nucleons means that nuclei of different Z (and N) have the same atomic mass (integer-wise), but they can obviously be different elements.

    For 4, what are the particular types of radiation emitted?

    Otherwise the answer seem mostly correct.
